BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Calibrachoa plant, botanically known as Calibrachoa sp. and hereinafter referred to by the name ‘Duecalhulpapi’.

The new Calibrachoa plant is a product of a planned breeding program conducted by the Inventor in Rheinberg, Germany. The objective of the breeding program is to create new uniform Calibrachoa plants with large and uniquely attractive flowers.

The new Calibrachoa plant originated from a cross-pollination made by the Inventor in July, 2013 in Rheinberg, Germany of a proprietary selection of Calibrachoa sp. identified as code number AA12-003572-002, not patented, as the female, or seed, parent with a proprietary selection of Calibrachoa sp. identified as code number AA12-002131-002, not patented, as the male, or pollen, parent. The new Calibrachoa plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Rheinberg, Germany in May, 2015.

Asexual reproduction of the new Calibrachoa plant by vegetative terminal cuttings in a controlled greenhouse environment in Rheinberg, Germany since July, 2015 has shown that the unique features of this new Calibrachoa plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Calibrachoa have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Duecalhulpapi’. These characteristics in combination distinguish ‘Duecalhulpapi’ as a new and distinct Calibrachoa plant:

-   -   1. Outwardly spreading to trailing and decumbent plant habit.     -   2. Vigorous growth habit.     -   3. Freely branching habit.     -   4. Early and freely flowering habit.     -   5. Large pink and red purple bi-colored flowers.     -   6. Good garden performance.

The new Calibrachoa can be compared to plants of the female parent selection. Plants of the new Calibrachoa differ primarily from plants of the female parent selection in flower color as plants of the female parent selection have pink-colored flowers. In addition, plants of the new Calibrachoa flower earlier than plants of the female parent selection.

The new Calibrachoa can be compared to plants of the male parent selection. Plants of the new Calibrachoa differ primarily from plants of the male parent selection in flower color as plants of the male parent selection have dark pink-colored flowers. In addition, plants of the new Calibrachoa are more vigorous than plants of the male parent selection.

The new Calibrachoa can be compared to plants of Calibrachoa sp. ‘Duecalhulapp’, disclosed in U.S. Plant patent application Ser. No. 14/999,899. Plants of the new Calibrachoa differ primarily from plants of ‘Duecalhulapp’ in flower color as plants of ‘Duecalhulapp’ have lighter pink-colored flowers. In addition, plants of the new Calibrachoa have thicker lateral branches and longer leaves than plants of ‘Duecalhulapp’.

Plants of the new Calibrachoa can also be compared to plants of Calibrachoa sp. ‘Duealroywi’, not patented. In side-by-side comparisons, plants of the new Calibrachoa differ primarily from plants of ‘Duealroywi’ in the following characteristics:

-   -   1. Plants of the new Calibrachoa have narrower leaves than         plants of ‘Duealroywi’.     -   2. Plants of the new Calibrachoa are more freely flowering than         plants of ‘Duealroywi’.     -   3. Plants of the new Calibrachoa and ‘Duealroywi’ differ in         flower color as plants of ‘Duealroywi’ have white-colored         flowers with purple violet-colored venation.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the summer in 12-cm containers in a glass-covered greenhouse in Rheinberg, Germany and under cultural practices typical of commercial Calibrachoa production. During the production of the plants, day and night temperatures averaged 18° C. and light levels averaged 4,500 lux. Rooted young plants were pinched one time three weeks after planting and were 13 weeks old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used.
